Description

Technical Field

[0001] The present application relates to a handle and a device including the handle. Background Art

[0002] It is known that in some heavy-duty mobile devices, in order to help users easily and labor-savingly push these devices, a boosting mechanism is usually provided. When the heavy-duty mobile device is in a stationary state, the boosting mechanism is usually in a locked state, that is, it does not play a boosting role. On the other hand, when a user wants to push the heavy-duty mobile device to move it, the locked state of the boosting mechanism is usually released by some means to make it in an unlocked state, so that, for example, the active force generated by the motor of the wheels installed on the heavy-duty mobile device can reduce the burden on the user. As an example of the mechanism for unlocking the boosting mechanism, a button provided on the handle is sometimes adopted. And, in order to facilitate the operation of the user and improve the reliability and convenience of unlocking the boosting mechanism, a handle including a handle base and a long strip-shaped button (or called a pressing member) is sometimes adopted. A vertical groove is formed in the handle base, and a protrusion is formed in the long strip-shaped button. In the case of adopting a handle with a long strip-shaped button, the boosting mechanism is unlocked by pushing or pressing the long strip-shaped button toward the handle base side to interact with a corresponding sensing element.

[0003] However, in the case of using a handle with the above structure, when the user pushes or presses the long strip-shaped button, the user often only pushes or presses a part of it. Therefore, when the user only pushes or presses a part of the long strip-shaped button, since the vertical groove and the protrusion are engaged with each other, the long strip-shaped button may be stuck when rotating around a certain contact part of the vertical groove and the protrusion under the action of the pushing force or the pressing force, and thus the boosting mechanism may not be unlocked smoothly. Summary of the Utility Model

[0004] The present application is formed in consideration of the above situation, and its purpose is to provide a handle that can smoothly press a long strip-shaped button toward the handle base side and can prevent the occurrence of jamming.

[0005] One technical solution of the present application provides a handle, including:

[0006] A handle base having a guiding hole;

[0007] A long strip-shaped pressing member; and

[0008] A positioning pin, one end of which is connected to the pressing member, and the other end of which can be in clearance fit with the guiding hole so that the pressing member can move relative to the handle base along the axis direction of the guiding hole.

[0009] According to the handle described in this technical solution, as an alternative to the combination of "groove" + "rib", by adopting the combination of "guide hole" + "positioning pin", the following situation can be avoided: during the process of pressing the long strip-shaped button, due to the inherent mechanical defects existing in the engagement of the groove and the rib (both the groove and the rib have discontinuous corners), the button may be stuck, resulting in the button being unable to be pressed to the desired position. More specifically, when pressing the long strip-shaped pressing member towards the handle base, the other end of the positioning pin connected to one end of the pressing member enters the guide hole formed in the handle base and has a clearance fit with the guide hole. This clearance fit enables the pressing member to move relative to the handle base along the axis direction of the guide hole and restricts the translation of the pressing member relative to the handle base in the plane orthogonal to the axial direction. At the same time, since the surface of the positioning pin and the inner wall surface of the guide hole are both relatively smooth surfaces, the relative rotation between the two is relatively smooth. Therefore, according to the handle described in this technical solution, it is possible to ensure that the long strip-shaped pressing member is pressed relative to the handle base to the desired position without getting stuck midway, while preventing unnecessary movement of the long strip-shaped pressing member relative to the handle base (for example, movement in the up and down, left and right directions).

[0010] Optionally, the handle further includes an elastic member, and the elastic member is disposed between the handle base and the pressing member.

[0011] According to the handle described in this technical solution, by making the handle have an elastic member, the pressing member can be switched between the initial position and the unlocking position, thereby realizing the unlocking of the assisting mechanism with a simple structure. It should be noted that the "unlocking position" mentioned here refers to the position where the locked state of the assisting mechanism can be released.

[0012] Optionally, the pressing member further forms an elastic member receiving hole for receiving one end of the elastic member.

[0013] According to the handle described in this technical solution, by providing an elastic member receiving hole in the pressing member, one end of the elastic member can be received inside the elastic member receiving hole. In this way, one end of the elastic member can be protected from damage, and at the same time, it also has a certain guiding effect on the elastic member.

[0014] Optionally, the handle further includes a photoelectric sensor, and the photoelectric sensor is disposed on the handle base. The pressing member forms a shielding portion for shielding the light emitted by the photoelectric sensor.

[0015] According to the handle described in this technical solution, when the light emitted by the photoelectric sensor is shielded by the shielding portion formed on the pressing member, the light receiving end of the photoelectric sensor will send an unlocking signal to the assisting mechanism because it does not receive the light emitted from the light emitting end, thereby enabling the unlocking of the assisting mechanism.

[0016] Optionally, the shielding portion is disposed at at least one end of the pressing member in the length direction thereof. The photoelectric sensor is disposed at a portion of the handle base corresponding to the at least one end of the pressing member.

[0017] Regarding the handle according to the present technical solution, considering that when the positioning pin is inserted into the guiding hole, the user can press any side of the strip-shaped pressing member. Therefore, by providing a shielding portion at at least one end of the pressing member in the length direction and providing a corresponding photoelectric sensor at a corresponding portion of the handle base, the user can unlock the assisting mechanism by pressing a part of the pressing member on the side where the end is located. In this way, the mechanism elements for unlocking the assisting mechanism can be flexibly set according to actual needs.

[0018] Optionally, the pressing member is formed with one of a protruding portion and a guiding groove portion extending along the length direction of the pressing member, and the handle base is formed with the other of the guiding groove portion and the protruding portion, and the protruding portion is inserted into the guiding groove portion.

[0019] Regarding the handle according to the present technical solution, by providing a protruding portion and a guiding groove portion extending along the length direction of the pressing member, when the pressing member is pressed toward the handle base side, the protruding portion and the guiding groove portion are engaged with each other. In this way, through the engagement of the protruding portion extending along the length direction with the guiding groove portion, the up-and-down movement of the pressing member relative to the handle base can be further prevented.

[0020] Optionally, the protruding portion includes a first protruding portion and a second protruding portion spaced apart from each other in the length direction. The guiding groove portion includes a first guiding groove portion for inserting the first protruding portion and a second guiding groove portion for inserting the second protruding portion, and when the protruding portion is formed on the pressing member, the guiding hole is disposed between the first protruding portion and the second protruding portion. When the guiding groove portion is formed on the pressing member, the guiding hole is disposed between the first guiding groove portion and the second guiding groove portion.

[0021] Regarding the handle according to the present technical solution, by respectively providing a protruding portion and a guiding groove portion on both sides of the positioning pin and the guiding hole, the up-and-down movement of the pressing member relative to the handle base can be prevented on both sides of the positioning pin and the guiding hole.

[0022] Optionally, both the protruding portion and the guiding groove portion continuously extend in the length direction, and when the protruding portion or the guiding groove portion is formed on the pressing member, the guiding hole is disposed at a portion of the pressing member at a different height from the portion where the protruding portion or the guiding groove portion is formed.

[0023] The handle according to the present technical solution is formed by continuously extending the protruding portion and the guiding groove portion, which facilitates processing.

[0024] Optionally, the positioning pin is a ball head positioning pin. The pin body end of the positioning pin is inserted into and connected to the pressing member, and the ball head end of the positioning pin is inserted into the guiding hole.

[0025] According to the handle of the present technical solution, by adopting a ball head positioning pin, while restricting the movement of the pressing member relative to the handle base by the abutment between the ball head positioning pin and the inside of the guiding hole, it can further prevent the pressing member from getting stuck during the pressing process.

[0026] Optionally, the handle base further forms a base side connection hole, and the pressing member further forms a pressing side connection hole corresponding to the base side connection hole. The handle base and the pressing member are connected by a connection pin inserted into the base side connection hole and the pressing side connection hole.

[0027] According to the handle of the present technical solution, when the handle base and the pressing member are connected together, the pressing of the pressing member toward the handle base can be performed, thereby preventing the pressing member from falling off unexpectedly during the pressing process.

[0028] Optionally, the handle further includes a handle cover. The handle cover is connected to the handle base and forms a space for arranging the pressing member.

[0029] According to the handle of the present technical solution, by accommodating the pressing member in the space formed by the handle cover, the aesthetic degree of the handle can be improved.

[0030] This application also provides a device at the same time, including the handle according to any one of the above technical solutions and an assisting mechanism connected to the handle. When the light emitted by the photoelectric sensor is not blocked by the shielding portion, the assisting mechanism is locked. When the light emitted by the photoelectric sensor is blocked by the shielding portion, the assisting mechanism assists the movement of the device.

[0031] According to the device of the present technical solution, since it can ensure that the pressing member is pressed relative to the handle base to the desired position without getting stuck halfway, the user can easily push the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0073] Hereinafter, with reference to Figures 1 to 7 , the specific structure of the handle according to an embodiment of the present application will be described.

[0074] Figure 1 FIG. shows an exploded view of the handle H according to an embodiment of the present application, Figure 3 FIG. shows a perspective view of the handle H in an assembled state, Figure 4 FIG. shows an assembly schematic diagram of each component of the handle H. As shown in Figure 1 , 3 and FIG. 4, the handle H is a component of, for example, a heavy-duty mobile device (abbreviated as device), and mainly includes a handle base 1, a long strip-shaped button (also referred to as a long strip-shaped pressing member, hereinafter simply referred to as a button) 2, and a positioning pin P.

[0075] The handle base 1 is for the user to hold and is connected to other components of the device. Specifically, from Figure 1It can be observed that two left - end - side connection holes 3 are formed at the left end portion of the handle base 1, and two right - end - side connection holes 4 are formed at the right end portion of the handle base 1. The left - end - side connection holes 3 and the right - end - side connection holes 4 are respectively connected to the member equipped with a force sensor through connection members such as rotary pins. As will be described later, in this state, when the long - strip - shaped button 2 is pressed towards the handle base 1 to a specified position, and when the handle base 1 is subjected to a forward thrust or a backward pull, the above - mentioned thrust or pull will be transmitted through the connection member and control the motor to apply a corresponding force to the wheels of the driving device, thereby driving the wheels to rotate. The above components constitute an assisting mechanism for assisting the user to push the device.

[0076] As Figure 1 shown, the handle base 1 mainly includes a straight portion 1A and a pair of curved portions 1B located on both sides of the straight portion 1A. A recessed space 1C is formed in the straight portion 1A. A guide hole 5 and a first guide groove portion 6A and a second guide groove portion 6B located on both sides of the guide hole 5 are formed at approximately the middle part of the central side wall of the recessed space 1C. The first guide groove portion 6A and the second guide groove portion 6B constitute the guide groove portion 6. The guide hole 5 is a hole with a certain depth in the pressing direction (i.e., Figure 1 the direction in which the handle base 1 faces the button 2), and can accommodate at least a part of the positioning pin P and have a clearance fit with it, so that the button 2 can move relative to the handle base 1 along the axis direction of the guide hole 5. Figure 5 shows an enlarged schematic view of the handle base 1 including the guide hole 6 and the first guide groove portion 6A and the second guide groove portion 6B. From Figure 1 and Figure 5 it can be observed that the first guide groove portion 6A and the second guide groove portion 6B are respectively formed by a pair of transverse sheets connected to the central side wall of the recessed space 1C and separated by a certain interval in the Figure 1 vertical direction. In addition, base - side connection holes 8 are respectively formed at the ends (i.e., the left - end portions) of the pair of transverse sheets on the left side of the guide hole 5 away from the guide hole 5 and at the ends (i.e., the right - end portions) of the pair of transverse sheets on the right side of the guide hole 5 away from the guide hole 5. The base - side connection holes 8 have an oval shape for the connection pin 9 to be inserted. By aligning the base - side connection holes 8 with the similarly oval - shaped pressing - side connection holes 14 of the button 2 and inserting the connection pin 9 through the base - side connection holes 8 and the pressing - side connection holes 14, the handle base 1 and the button 2 can be connected together in such a way that they can move a certain distance in the pressing direction within the range of the holes of the base - side connection holes 8 and the pressing - side connection holes 14. And, a first photoelectric sensor 7A and a second photoelectric sensor 7B are respectively connected to the part of the central side wall of the recessed space 1C that is to the left of the first guide groove portion 6A and to the right of the second guide groove portion 6B (as Figure 7As shown, the first photoelectric sensor 7A and the second photoelectric sensor 7B are sometimes referred to as the photoelectric sensor 7 without distinction in this text. As Figure 7 shown, the photoelectric sensor 7 includes a light emitting end and a light receiving end, and senses a target object by whether the light receiving end receives the light emitted from the light emitting end. On the end faces of a pair of bent portions 1B on both sides of the straight portion 1A, a pair of fixing grooves 1D are formed that bend and extend from the left and right ends of the handle base 1 to the straight portion 1A, and the pair of fixing grooves 1D are for fitting and fixing the fixing protrusions of the handle cover C.

[0077] The long strip-shaped button 2 is a member that cooperates with the handle base 1 to unlock the above-mentioned boosting mechanism. As Figure 1 shown, compared with a general button, the size of this button 2 in the left-right direction (referred to as the length direction) in the figure is significantly larger than the sizes of the other two directions orthogonal to this length direction, so this button 2 is called a long strip-shaped button. Figure 2 The specific structure of the part of the long strip-shaped button 2 on the side close to the handle base 1 is shown. Combining Figure 1 and Figure 2 it can be known that the button 2 is a hollow and long strip-shaped member that opens toward the side of the handle base 1. As Figure 2 shown, on the upper surface and the lower surface of this button 2, an upper protruding portion 10A and a lower protruding portion 10B that protrude toward the side of the handle base 1 are respectively formed, and on the surface of the side wall of this button 2 that extends in the length direction (i.e., Figure 1 and Figure 2 the left-right direction in the figure) on the side close to the handle base 1, an intermediate side protruding portion 10C (also simply referred to as the protruding portion 10C) is formed corresponding to the upper protruding portion 10A and the lower protruding portion 10B, and the intermediate side protruding portion 10C is used to engage with the guide groove portion 6 formed on the handle base 1. In addition, the interval between the upper protruding portion 10A and the intermediate side protruding portion 10C is greater than the thickness of the upper horizontal sheet, which is the horizontal sheet located on the upper side among the pair of horizontal sheets, so that when the intermediate side protruding portion 10C is inserted into the guide groove portion 6, the upper protruding portion 10A is located above the upper horizontal sheet. Similarly, the interval between the lower protruding portion 10B and the intermediate side protruding portion 10C is greater than the thickness of the lower horizontal sheet, which is the horizontal sheet located on the lower side among the pair of horizontal sheets, so that when the intermediate side protruding portion 10C is inserted into the guide groove portion 6, the lower protruding portion 10B is located below the lower horizontal sheet. And, as Figure 2As shown, a positioning pin connection hole 11 is formed at a substantially middle portion in the longitudinal direction of the middle side protrusion 10C. One end of the positioning pin P is inserted and fixed into the positioning pin connection hole 11, which is, for example, a blind hole. Due to the formation of the positioning pin connection hole 11, the middle side protrusion 10C is divided into a first middle side protrusion 10C1 and a second middle side protrusion 10C2 by the positioning pin connection hole 11. In addition, the "substantially middle portion" mentioned here refers to the portion that aligns with the portion of the handle base 1 where the above-mentioned guide hole 5 is formed in the pressing direction when the button 2 is pressed toward the handle base 1. In other words, the guide hole 5 and the positioning pin connection hole 11 are arranged to be aligned with each other. In addition, a pair of elastic member receiving holes 12 are formed on the right side of the first middle side protrusion 10C1 and the left side of the second middle side protrusion 10C2. The elastic member receiving holes 12 are holes for receiving one end of the elastic member 15. By receiving one end of the elastic member 15 in the elastic member receiving hole 12, it is possible to prevent the situation where one end of the elastic member 15 is damaged due to being exposed. And, a pair of shielding portions 13, namely a first shielding portion 13A and a second shielding portion 13B, are also formed at the portion of the above-mentioned side wall that is outside the pair of elastic member receiving holes 12 and corresponds to the photoelectric sensor 7. The first shielding portion 13A and the second shielding portion 13B are parts that block the light emitted from the light emitting ends of the first photoelectric sensor 7A and the second photoelectric sensor 7B respectively when the button 2 is pressed toward the handle base 1 side. From Figure 2 It can also be observed that pressing side connection holes 14 are formed at the end portions on the left and right sides of the upper side protrusion 10A, the middle side protrusion 10C, and the lower side protrusion 10B in an aligned manner. As described above, by aligning the oblong base side connection hole 8 with the similarly oblong pressing side connection hole 14 of the button 2 and inserting the connecting pin 9 through the base side connection hole 8 and the pressing side connection hole 14, the handle base 1 and the button 2 can be connected together in such a way that they can move a certain distance in the pressing direction within the range of the holes of the base side connection hole 8 and the pressing side connection hole 14.

[0078] As Figure 1As shown, the handle H further includes a pair of elastic members 15 and a handle housing C. The pair of elastic members 15 are arranged between the handle base 1 and the pressing member 2. In this embodiment, one end of the elastic member 15 is received in the above-mentioned elastic member receiving hole 12, and the other end abuts or is connected to the side wall of the recessed space 1C of the straight portion 1A of the handle base 1. Thus, when the button 2 is pressed toward the handle base 1 side, the elastic member 15 is compressed, and when the button 2 is released, the elastic member 15 undergoes a recovery deformation under the action of the restoring force, thereby driving the button 2 back to the initial position. The handle housing C includes a middle portion C1 and a pair of side end portions C2 located on both sides of the middle portion C1. A notch space S for receiving the button 2 is formed in the middle portion C1, and fixing protrusions (not shown in the figure) for engaging with the fixing grooves 1D formed on the end faces of the bent portions 1B of the handle base 1 are formed on both of the pair of side end portions C2 located on both sides of the middle portion C1. Thus, by moving the handle housing C from the Figure 1 upper side in the figure toward the handle base 1 so that the fixing protrusions engage with the fixing grooves 1D, the handle housing C is mounted to the handle base 1. Figure 3 The perspective view of the handle H in the assembled state is shown.

[0079] Regarding the positioning pin P, for example, a ball head positioning pin can be used. The ball head positioning pin includes a pin body end and a ball head end. In this case, the pin body end of the ball head positioning pin is inserted and connected to the positioning pin connection hole 11 of the button 2, and the ball head end of the ball head positioning pin is inserted into the guide hole 5 of the handle base 1. However, as the positioning pin P, it is not limited to the ball head positioning pin. As long as one end of the positioning pin can be in clearance fit with the guide hole 5 so that the button 2 can move along the axis direction of the guide hole 5 relative to the handle base 1 and the movement of the button 2 relative to the handle base 1 in the left-right direction (i.e., the length direction) and the up-down direction orthogonal to the above-mentioned axis direction can be restricted, other types of positioning pins can also be used.

[0080] Next, on the basis of the above description of the specific structure of the handle H, how to unlock the assist mechanism by operating the handle H will be described.

[0081] First, the user holds the handle H and applies a pressing force to the long strip-shaped button 2. Under the action of the pressing force, the button 2 moves from the initial position toward the side of the handle base 1. During this movement, the other end of the positioning pin P enters the guide hole 5 to form a clearance fit, and the middle-side protrusion 10C of the button 2 engages with the guide groove portion 6 of the handle base 1. At this time, the button 2 can move to a certain extent in the pressing direction, and when the button 2 is to move relative to the handle base 1 in the left-right direction or the up-down direction, the movement in the left-right direction and the up-down direction is restricted because the surface of the positioning pin P abuts against the inner wall of the guide hole 5. At the same time, since the middle-side protrusion 10C engages with the guide groove portion 6, the relative movement of the button 2 relative to the handle base 1 in the up-down direction is also restricted by this engagement, thereby further restricting the occurrence of undesired relative movement in the up-down direction.

[0082] As Figure 6 shown, when pressing the button 2 toward the side of the handle base 1 such that at least one of the pair of shielding portions 13 of the button 2, i.e., the first shielding portion 13A and the second shielding portion 13B, has blocked the light emitted from the light-emitting ends of the first photoelectric sensor 7A and the second photoelectric sensor 7B, the light-receiving ends of the first photoelectric sensor 7A and / or the second photoelectric sensor 7B cannot receive the light emitted from the light-emitting ends. Specifically, sometimes, since the user's hand is mainly held on one side (left or right) of the handle base 1 and the button 2, when the user presses the button 2 toward the side of the handle base 1, only the first shielding portion 13A located on the left side of the button 2 or only the second shielding portion 13B located on the right side of the button 2 is pressed toward the side of the handle base 1, so that only the light-receiving end of the first photoelectric sensor 7A or the second photoelectric sensor 7B cannot receive the light emitted from the light-emitting ends. On the other hand, sometimes, the user's hand just holds the approximate middle portion of the handle base 1 and the button 2, so when the user presses the button 2 toward the side of the handle base 1, the first shielding portion 13A and the second shielding portion 13B located on both sides of the button 2 are simultaneously pressed toward the side of the handle base 1, so that the light-receiving ends of both the first photoelectric sensor 7A and the second photoelectric sensor 7B cannot receive the light emitted from the light-emitting ends. At this time, the first photoelectric sensor 7A and / or the second photoelectric sensor 7B sends an unlocking signal to the boosting mechanism. After the boosting mechanism receives this unlocking signal, the boosting mechanism drives the wheels of the device to rotate at a set speed. Thus, due to the above structure, pressing the button 2 at any position of the button 2 can trigger the unlocking of the boosting mechanism. Therefore, when the user applies a small pushing force or pulling force to the device, the device can be moved.

[0083] On the other hand, when the user has pushed or pulled the device to the specified location, if the user no longer applies a pressing force to button 2 and releases it, then, under the action of the restoring force of the elastic member 15, button 2 moves in a direction away from the handle base 1, and the first shielding portion 13A and / or the second shielding portion 13B no longer block the light emitted from the light emitting ends of the first photoelectric sensor 7A and the second photoelectric sensor 7B. At this time, the light receiving ends of the first photoelectric sensor 7A and the second photoelectric sensor 7B receive the light emitted from the light emitting ends again, thereby sending a locking signal to the boosting mechanism. In this way, the boosting mechanism is locked again.

[0084] For the handle H according to the present embodiment, compared with the existing handle H that restricts the left-right movement of the pressing member relative to the handle base by the engagement of the vertical groove and the vertical protrusion, by making one end of the positioning pin P have a clearance fit with the guide hole 5, button 2 can move relative to handle base 1 along the axis direction of guide hole 5 and the movement of button 2 relative to handle base 1 in the length direction and the up-down direction orthogonal to this axis direction is restricted, it is possible to ensure that during the pressing process, button 2 will not have unnecessary left-right movement or up-down movement relative to handle base 1, while preventing the situation where button 2 gets stuck due to improper pressing.

[0085] (Other embodiments)

[0086] In the above embodiment, the case where the guide groove portion 6 includes the first guide groove portion 6A and the second guide groove portion 6B separated by the guide hole 5 and located on both sides of the guide hole 5 is taken as an example for illustration, but it is not limited thereto. The guide groove portion 6 can also be arranged in a manner not divided by the guide hole 5. For example, it can be that at the side wall of the recessed space 1C of the straight portion 1A of the handle base 1, the guide groove portion 6 and the guide hole 5 are formed at different heights, so that the guide groove portion 6 can be a continuous guide groove portion. Correspondingly, the protruding portion 10C can also be arranged in a manner not divided by the positioning pin connection hole 11. For example, the protruding portion 10C and the positioning pin connection hole 11 can be formed at different heights, so that the protruding portion 10C can be a continuous protruding portion.

[0087] In the above embodiment, the case where button 2 includes the positioning pin connection hole 11 into which one end of the positioning pin is inserted and connected is taken as an example for illustration, but it is not limited thereto. Button 2 may not include such a positioning pin connection hole 11, and one end of the positioning pin can be directly fixed to the side wall of button 2.

[0088] In the above embodiment, the case where the protruding portion 10C is formed on button 2 and the guide groove portion 6 is formed on the handle base 1 is described, but it is not limited thereto. For example, it can also be that the guide groove portion 6 is formed on button 2 and the protruding portion 10C is formed on the handle base 1. In this way, the same technical effect can also be achieved.

[0089] In the above-described embodiment, the case where the button 2 further includes an elastic member receiving hole 12 for receiving one end of the elastic member 15 has been described as an example, but it is not limited thereto. The button 2 may not include the elastic member receiving hole 12, and one end of the elastic member 15 may be directly fixedly connected to the wall portion of the button 2.
